There are 65 of my photo shows stuck in a Corel/Roxio PhotoShow program that issued an "End-of-Life" two years ago. I hope to retrieve them through another program if possible. I haven't been able to through Roxio at all.
it is very unlikely that you will be able to retrieve the projects in any other program as there is no universal format between different brand editors.

AFAICS though the program is EOL it should still function on your PC. If so can the program export to MOV* or MP4 h.264, AAC encoding?
* MOV file format and the original FLV exports can be converted to MP4 h.264, AAC encoding ,for maximum compatibility, using a program such as Handbrake.
